Here...
I got valium before mine also... It was to ensure the Dr. didn't have a nervous patient. It worked, I was good to go.
15 minutes in the Dr's office, a weekend watching movies, and no pain killers needed. I did have some nut aches for a while, but all subsided.

The Dr. invited my girlfriend of the time, now wife, to watch. We all got my balls clipped together.
